Fuel injectors are responsible for regulating how much fuel the engine needs to burn. They work in strenuous conditions, unfortunately, which can cause them to get dirty, clogged, or cracked.
When fuel injectors fail, they cause a bunch of problems that can affect the performance engine performance; worse, it can lead to major damage if you do not diagnose, repair, or replace the fuel injector as soon as possible.
These signs of a failing fuel injector could come in handy:
Abrupt Engine Power
It’s a no-brainer: clogged fuel injectors lead to irregular fuel supply. With such irregular and lopsided flow, the engine will alternate between low and high revolutions per minute (RPMs), which can cause it to provide power in big, inefficient chunks instead of the normal smooth and gradual delivery.
The clogging of foreign particles might wear out the injector. When this happens, the injector might miss supplying fuel when it needs to, which can lead to poor engine performance. The engine will misfire. You can easily feel this while you drive the car.
This is a very bad sign, and you need to fix the problem immediately. If you don’t, the engine might overheat and ignite the fuel mixture.
Rough and Irregular Idle
Damaged fuel injectors will cause problems on the go, but it can also cause problems even when the engine is running idle. When the engine provides the power in big chunks, the engine idle will be rough and irregular.
Fuel Leaks and Reduced Gas Mileage
External cracks are common on fuel injectors, especially those fitted onto the intake manifold. This might cause the fuel to leak instead of running through the nozzle. This will weaken the air fuel mixture and provide poor engine efficiency.
It’s obvious that with leaks, you are wasting fuel, which means you are also reducing the gas mileage of the car.
Starting today, watch out for these signs. Responding to the problem as early as possible can save a huge amount of time and money; it can also help you avoid damage to other parts of your vehicle.
